Fervent
(dalaq; ektenes, zeo):
"Fervently" is the translation of agonizomai, "to strive or struggle" (agonize), Col 4:12 the King James Version, the Revised Version (British and American) "Epaphras .... striving for you in his prayers"; of ektenos, literally, in an outstretched manner (1Pe 1:22, the Revised Version (British and American) "Love one another from the heart fervently"; compare 1Pe 4:8, "fervent in your love among yourselves"). Christian love too often lacks this fervency, but Christ’s love for us was "stretched out" to the uttermost.
The Revised Version (British and American) has "fervently" for "earnestly" (Jas 5:17, margin "with prayer").
